Title: Improvements in or relating to gun mountings
IPC: F41G1/393
Filed: 1943-11-18
Abstract: 578,756. Aircraft gun turrets. RICE, E. A. B., ROSE, A. G., C U R T I S, S., NICHOLLS, K. H., and ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 18, 1943, No. 19260. [Classes 92 (i) and 92 (ii)] Relates to gun mountings of the type in which pivotal movement of the gun or guns, such as the guns 11 in the construction shown, is controlled by a sighting arm 27 adapted, when moved, to bring into operation power actuated mechanism, such as oil motors 19, which causes the gun or guns to move substantially as one with the sighting arm. According to the invention the sighting arm is connected to controlling mechanism 21 of the power-actuated elevation mechanism 19 by means comprising an operating link 29 forming a part of a parallel motion linkage connecting arm 27 with an intermediate device 31, 32 pivoting about an axis parallel to the elevating axis of the guns. The device 31, 32, is connected by further parallel motion linkage 37 to an actuating member 36 freely mounted about the elevation axis of the guns and connected, by a link 41 and arm 42 for example, to the controlling mechanism 21. The link 29 is disposed with its axis substantially parallel to the training axis of the guns. By the above arrangement the danger of the controlling mechanism 21 being actuated upon initial training movement of the sighting arm is avoided. In the construction shown, the invention is applied to the gun turret forming the subject of Specification 577,904 wherein the guns 11 are mounted on bearing members 14 attached to the rotatable platform 16 of an aircraft turret. The arm 27 carrying sight 30 is U-shape in plan and is pivoted at 26, adjacent the end of each limb, on an operating member 24 which moves about the training axis of the turret. Movement of the sight, and hence of member 24, in training actuates a valve 22 controlling an oil motor for rotating the platform. Movement of the arm about axis 26 in elevation actuates motors 19 through controlling mechanism 21 as described above. The device 31, 32, which is in the form of a two armed pivoted lever, has its arm 31 of the same radius as the arm connecting link 29 with the sighting arm, while the link 37, when in its neutral position, has its centre line disposed as a common tangent to the, ares of movement of the pivotal points at which it is connected to member 36 and arm 32. The Provisional Specification refers' also to Specification 576,621.

Title: Manufacture of combustible gas
Inventor: PHILLIPPS IAN HUGH
IPC: C10K3/02
Filed: 1966-05-03
Abstract: A fuel gas made by continuously reforming a hydrocarbon, e.g methane, with steam in externally heated catalyst filled tubes, is mixed with substantially sulphur-free flue gases and the mixture passed with steam over a catalyst to convert CO in the mixture to CO2. The flue gases may be those from the reformer, and the CO-conversion catalyst is chromia-promoted iron oxide.  Gaseous hydrocarbon, e.g. methane, may be added to the converted gas.  In an illustrated embodiment, a supply of methane is divided into three portions, namely: for gasifying, for heating the reformer, and for enriching the converted gas, and the hot flue gases serve to raise steam for the reformer before being compressed and mixed with the fuel gas.

Abstract: 1,003,884. Katharometers. CAMBRIDGE INSTRUMENT CO. Ltd. May 15, 1962 [May 31, 1961], No.19615/61. Heading G1N. A katharometer for gas analysis by comparing the thermal conductivity of a carrier gas with that of a mixture of the carrier gas and a test gas as measured by the difference in temperature and resistance of resistor elements heated by the same current but located in the respective gases, is characterised by means for automatically compensating for variations in the thermal conductivities of the carrier gas. As shown (Fig. 2) the katharometer comprises a bridge network of four elements, A and C being located in the carrier gas and B and D being located in the carrier plus test gas mixture. Two additional resistor elements E, F are convected in parallel with the bridge arms through a rheostat R, F being in a chamber containing the carrier gas, and E in a reference gas. All the chambers are initially filled with the reference gas, potentiometer G is adjusted for zero potential difference between junctions 2, 3 and potentiometer H for zero p.d. between junctions 1, 2. All the chambers but that containing element E are then filled with the carrier gas and any unbalance of the bridge is eliminated by adjustment of rheostat R, which may be connected to junction 2, as shown, or to junction 3. The network will now compensate for small differences between elements A, B, C, D with changes in the thermol conductivity of the carrier gas. The bridge may be fed with D.C. or A.C. using a centre-tapped-transformer winding S, T (Fig. 4).

Class 85 The method of preparing a composition for admixture with well-drilling mud described in the parent Specification is modified in that a tannin-containing bark such as mangrove bark or wattle bark is used in the place of a tannin. The bark is shredded and fed into aqueous alkali metal hydroxide solution, preferably sodium hydroxide solution, the alkali being in excess of that required to produce a neutral product and the mixture is boiled and dried. Insoluble or soluble adsorbents may, particularly when the alkali content is high, be added to the mix as in the parent process. When the woody, fibrous content of the bark used is high, however, the contents of adsorbents may be reduced or they may be eliminated.

Abstract: 579,338. Electrical transformation of co-ordinates. COSSOR, Ltd., A. C., BEDFORD, L. H., BELL, J., and LANGHAM, E. M. Nov. 30, 1942, No. 2001/43. Divided out of 579,325, [Group XIX]. [Class 40 (i)] [Also in Group XIX] The invention relates to apparatus for the electrical transformation of two - dimen - sional cartesian co-ordinates into two - dimensional polar co-ordinates. As shown, alternating voltages proportional to x and y, i.e., R cos A and R sin A, are developed by modulators 15, 16 and are opposed by cophased alternating voltages r cos B and r sin B developed by a magslip resolver 30 and ganged linear potentiometers 3, 4, set respectively to the angle B and to a position representing r. The resultant potentials energise transformers 5, 50, the outputs of the secondaries of which are fed to amplifiers 8, 18 which feed the two-phase primary windings 20, 21 of a further magslip 27 mechanically coupled to the first, so that they are set to the same angle. When the settings of the magslip resolver 30 and the potentiometer 3, 4 are nearly correct, the voltages across windings 23, 24, indicated on meters 25, 26 are proportional respectively to the errors in the settings of the resolver 30 and the potentiometer 3-4. The errors can be rectified manually, or the meters 25, 26 can be replaced by servo-motors operating the magslip resolver and the potentiometer in the appropriate sense to reduce the controlling secondary voltage. The apparatus is incorporated in the predicting apparatus described in Specification 579,325, [Group XIX]. The meters 25, 26 may be of the type described in Specification 579,337, [Group XXXVI].

The system operates on a succession of samples of the analogue input and each sample period is divided into a short analogue to digital conversion period and a longer digital filtering period. The processor comprises a series of cells C 0 -C n  controlled from the programmable control unit 25. (For programme details see Specification). The analogue to digital conversion is of the successive approximation type wherein an arbitary digital value is generated, and converted to an analogue signal which is compared with the input. The digital signal is then successively modified in a direction determined by the comparator output until the digital value is correct. The digital filtering is carried out using a known Z-pole-Z-zero filter. Digital to analogue converter 29 is of the resistance type.
